Example complaints

“Both struts went out on the car at once. When we went to the dealer, we were told that there were no struts in the country, and they have no idea when they will be available. When we called back this week to check on the progress, there is no progress at all. We have had to rent a vehicle, which we did for a month's time not knowing how long this may go on.”
NHTSA complaint #11417896, filed 2021-05“2018 Yukon Denali engine failed June 2024 due to the lifter being bent. The dealership Richey Cadillac in Daytona Beach estimated the repairs at $18,862 and were going to have my vehicle for months. I took it to my mechanic who rebuilt the engine for $7181 in 30 days. My safety was placed at risk because while driving I had to pull over since I had no control with the engine failure. There were no messages prior to the failure.”
NHTSA complaint #11660917, filed 2025-05“I own a 2018 GMC Denali, Yukon XL SUV, with 67k miles. While towing our 24’ Airstream (weight 4400 lbs) the vehicle excessively bounced in the air several times on a flat pull on I-80 in Northern Ca. I took it to three mechanics who told me that the front magnetic and rear air shocks had all failed and were leaking oil. The best price that we could secure for replacement is $2500. Each mechanic commented about the frequency of this type of failure with GMC and stated that this should be a recall because of the risk of trailer detachment/failure. …”
